为进一步降低试验成本、提高试验效率,结合静力相似理论,提出了缩尺模型混合模拟试验方法.该方法在满足模型与原型材料相同条件下,理论推导出试验子结构所需的位移及反力相似条件,仅对试验子结构输入输出参数进行相似处理,运动方程及计算子结构相应参数与原型完全相同,来实现混合模拟试验.采用MATLAB和Open SEES混合编程方法,实现了传统子结构混合模拟试验(包括剪切型、弯剪型、弯曲型模型)以及分布子结构混合模拟试验.相应足尺模型数值模拟结果比较,验证了本文所提方法的可行性.
In order to further reduce the test cost and improve the test efficiency, combined with the static similarity theory, a hybrid simulation test method for the scale model is proposed.This method can theoretically deduce the displacement and the inverse of the substructure under the same condition of the model and the prototype material Similar conditions of force, only the input and output parameters of the experimental sub-structure are treated similarly, the equations of motion and the corresponding parameters of the calculated sub-structure are exactly the same as that of the prototype, so as to realize the mixed simulation test. By using MATLAB and Open SEES mixed programming method, Simulation experiments (including shearing, bending shear, bending model) and distribution substructure mixed simulation test are carried out.The numerical results of the corresponding full-scale model are compared to verify the feasibility of the proposed method.
